A Straight Line Route Survey Which Had Pis At 3 81 27 12 30 And At 5 42 30 10 56 2846875

A straight-line route survey, which had PIs at 3 + 81.27 (? = 12°30) and at 5 + 42.30 (?= 10°56), later had 600-ft-radius circular curves inserted at each PI. Compute the BC and EC stationing (chainage) for each curve.
